WATER-CLOSET VALVE.

Specification of Letters Patent.

Patented March 24, 1908.

Application filed June 22, 1966. Serial No. 322,892.

Be it known that I, PHILIP HAAs, citizen of the UnitedStates, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Water-Closet Valves; and I do ereby declare the following to be afull, clear,

and exact description of the invention, such as will enable others skilled in' the art to which it appertains to make and use the same.

My invention consists in the novel features hereinafter described, reference bein had to the accompanying drawings which-i1 ustrate one form in which I have contemplated embodying my invention and certam modifications thereof, and said invention is fully disclosed in the following specification and claims.

Referring to the said drawings, Figure 1 is a vertical sectional view of a water closet valve, embodying my invention, showing the parts in normal or closed {position Fig. 2 is valve.

a similar view showing t e positions of the parts, as they would appear after the push utton has been 0 erated, and the main valve opened to flus the closet. Fig. 3 is a front elevation, drawn to a slightly reduced scale, of one of the parts of the casing or shell of the apparatus, showing the inner face there of. Fig. 4 is a detail elevation of the main Fig. 5 is an elevation of the other. part of the casing, showing the inner face of the same. Fig. 6 is an exterior view of the entire apparatus. Fig. 7 is a detail view of three of the washers used for adjusting the apparatus to regulate the duration of the flow. Fig. 8 is a sectional view similar to Figs. land 2, and drawn to the same scale, showing a slightly modified form of my invention, and including a cut off valve for the water supply. Fig. .9 is a rear. elevation of the apparatus shownin Fig. 8 drawn to the same' scale as that used in Figs. 3 to 6 inclusive, and showing said out ofl valve. Fig. 10 is a detail sectional view of the devices for supporting and operating said out off valve. Fig. 11 is a partial vertical sectional view similar to Figs. 1 and-2 and drawn to the same scale,- showing another slightly modified form of the invention.

Referring to the form of my invention shown in Figs. 1 to 7 inclusive, thecasing of the apparatus is conveniently formed in two parts A and B, between WhlC-ll are clamped,

- the marginal portions of the main valve C,

the latter being composed of rubber, and constructed as hereinafter described. The A of the casing is provided with aho low chamber a within the same, surrounding an annular flange 11/ forming a water inlet passage. ()n the inner face of the annular flange a is formed a valve seat a and said valve seat is connected to the outer wall of the part A by an annular web 0, provided art with numerous apertures or slots, a communicating with the interior chamber a. This annular erforated web a erforms an important unction in supporting the portions of the main valve 0, surrounding the central ortion, and thus prevents the bulging and bursting of the valve, as will be clearly seen in the drawings. The rear wall of part A is provided with a water inlet aperture (1 (pref? erably screw threaded to receive a pipe connected to the water main or supply) and the lower portion of part A is provi bular extension af externally threaded for connection to the closet bowl. The part'A is also provided on its inner face near the extension at with an aperture a, the urpose of which will be hereinafter explained The part B ofthe casing is provided with a chamber b, which I term the back ressure chamber, and which is located on t e front side of the main valve C. The part B is also provided with an exterior chamber b of reduced diameter which communicates with the chamber 1), by an aperture b having a valve seat I) on-its inner face, and the exterior 'of said extension is-threaded as shown to receive a cap I). 6 represents a bypass formed in the part B exterior to the chamber b, and extending from the exterior chamber b, to an aperture b, adapted to register with the aperture a of art A ofthe casing.

C represents t 0. main valve of the apparatus which is in the form of a diaphragm and is preferably composed of rubber, the marginal portions being clamped between the two parts A and B of the casing and also serving as packing therefor. The valve C ed with a tuone side thereof.

seats, it will ractically do so throu hout, and thus avoi the flutterin of the va ve, or portions thereof which mig t otherwise occur. I refer to reinforce this valve by means 0 a flat circular disk or ring 0 which is molded and vulcanized in the body of the valve, and is preferably of such diameter as to extend over the seat a, although the valve may be reinforced in other ways. 7 In this instance the valve C is shown provided with a central aperture, having a metallic bushing a therein, and I prefer to form this bushing integrally with the reinforcing disk or ring (1 as shown in Figs. land 2, and vulcanize the same in the rubber portion of the valve, although they need not of necessity be integral.

D represents the relief valve, for the back pressure chamber 1), and is preferably formed as shown in Figs. 1 and 2, the valve being formed of a metal shell provided with a central threaded a erture, and with an annular recess surroun ing saidaperture, in which is located an annular rubber packing d, which is preferably molded and vulcanized into the metal shell, and projects from the shell on The valve D is screwed upon a stem (1 consisting of radially 'disposed wings, leaving passages between the same, and said stem is provided with an exterior threaded portion (1 which extends throu h a washer d and a rubber diaphragm d, an is engaged by an exterior push button E, the stem of which extends throu h a central aperture in the cap I). The ru ber diahragm d has its mar inal portions clamped etween thecap b an the end of the extension or chamber 1), and serves the function of preventing leakage, while permitting the longitu dinal movements of the push button E and valve stem (1, without the use of a stuffing box. oZ represents a spring interposed between the inner wall of chamber 6 and the washer (Z in rear of diaphragm d, which presses the valve stem (2 outwardly and holds valve D upon its seat.

In order to render the apparatus operative, it is necessary to provide for a reduced passage for water from the water supplypassage (within the flange a) to the back pressure chamber. I provide this passage in this instance by means of the central aperture in the sleeve or bushing 0 in the main valve, which I term the controlling sleeve, and a controlling stem F which extends through said bushing but is of slightly less diameter than the aperture in the bushing, thus providing an annular passage, (which is merely an infinitesimal crevice) between the stem and'bushing. In the drawings I have been obliged to greatly exaggerate the showing of this annular passage, in order that its location may be properly understood, but in practice it is found that if the engagement of the stem F, and bushing or sleeve 0 is What .this is my preferred construction at the present time although the said stem may be otherwise supported if desired, one other arrangement for this purpose being shown in Fig. 11, and hereinafter described.

In the form of my invention shown in Figs. 1 and 2 the annular flange a, is shown provided internally with a spider or cross ar a having a guiding aperture therein for the controlling stem F but this is not essential.

I will now describe the operation of my invention having special reference to the form shown in Figs. 1 to 7 inclusive. The apparatus being connected to the water supp y pipe and closet bowl, as before indicated, the water enters the casing at a into the water space within the annular flange a, and also. trickles or forces.its way through the annular controlling passa e, between the stem F and sleeve 0 into t e back pressure chamber 6, from which it cannot escape so lon as the relief valve D is closed. As soon as 5w chamber 1) becomes filled the pressure therein will equal that within the water inlet passage, and chamber 1) being of the greater diameter, the pressure therein will be exerted upon nearly the entire area of the main valve C, thus closing it and maintaining it against the pressure 'of the incoming water. This position of the parts is shown in Fig. 1 and is the normal condition of the apparatus, no water being ermitted to flow to the closet.

To flush t e closet, the push button E is pressed inwardly, thus opening the relief 'valve D, and allowing the water in the back pressure chamber 1) to discharge through the bypass b I The pressure of water on'the other side of the valve 0 will instantly open the valve, and the water from the main will pass through the apertures a a into chamber a and thence to the closet, thus providing a practically unobstructed passage of large area. When the main valve opens it moves quickly into engagement with the rearface of the relief valve D under the pressure of the water inthe main, and tends to close said rellef valve.

If the pressure of the Water is sufficient it will instantly close the relief valve even against the pressure of the finger on the push button, otherwise as soon as the pressure is removed from the push button the spring (1 will seat the relief valve. The closing of the relief valve closes the exit from the back pressure chamber, which will slowly fill up by the percolation of water throu h the annular controlling passage and gra ually accumulating pressure until the valve 0 is forced. into closed position, thus cutting off the flow.

It is obvious that the duration of the flow will depend upon the size of the annular conpressures a number of washers K (preferably of brass) shown in detail in Fig 7, asuitable number of which can be placed upon the stem F between the outer end of the sleeve 0 and the relief valve D to limit the opening movement of the valve C at the proper point.

' It will be understood that the greater the distance which the main valve C opens, the more water will be dischar ed from the back pressure chamber and the onger it will take to refill said chamber, and the longer the By limiting the opening of the valve more or less the duration of flow can be regulated to suit the pressure of the water in the main with which the apparatus is connected.

I For low water pressures, it may sometimes be desirable to increase the slze of the annular controlling passage, which can be contained in the 'Water.

done by slightly reducing the controlling stem with emery paper or otherwise. It is to be noted that by providing a controlling passage between the sleeve 0 and the stem F, a very important function is performed each time the device is operated, to wit the cleaning of the controlling passage.

In the form of the invention shown in Figs. 1 to 7 inclusive, several relative movements take place between the sleeve 0 and stem F each time the device is operated, the relative movement of the parts and the consequent exposure of the previously covered surface of the stem F to the water serving to keep this passage free from accumulation or sediment, no matter how much solid matter may be when the push button is pressed in the stem F is pushed rearwardly through the sleeve 0 (3) the opening movement of the valve C causes the sleeve 0 to slide forwardly over the stem; (4) the closing of the valve C after the relief valve D is closed, causes the sleeve 0 to slide rearwardly over the stem. The relative movements of the controlling sleeve and stem and the consequent exposure of the portions of the stem, normally within the sleeve to the water will thus keep this passage cleanand insure a perfect operation of the device, even. if it has not been used for a considerable time, and I consider this a very important feature of the invention. Obviously, it is not essential that the aperture in the sleeve and the exterior of the stem .should be round '(thusforming an annular Thus (1 and 2).

operated device extending to the outside of the casing, so that the apparatus can be disconnected from the water supply to permit of examination or repair hen necessary.

vvithout cutting-off the eater sup ly of the entire building in vv hich the device is located. A rear view of the apparatus illustrated in Fig. 8 is shovvn on a smaller scale in Fig. 9.

and Fig. 10 shovvs a detail section of the cutoff valve and its operative connections. ferring to these figures, the rear part. of the casing, here lettered A, is constructed substantially like the part A shovvn in the other figures except that the annular flange (1", which for convenience is termed the inlet passage, is provided at its inner end ith the seat a to receive the main valve C and at its outer end with an exterior valve seat a to receive the cut-off valve, and said casing section A is provided \vltil an elliptical chan1- her a which contains the cut-off valve. The rear face of this valve chamber a" is provided with a threaded aperture a to receive the water supply pipe. Within the valve chamber a is located a quick acting gate valve including among its members the follovving elements. G represents the valve proper which is preferably a metallic disk provided on its rear face ith a central stem g.- H represents the pivot stem of the valve which is provided at its lower end ith a reduced bearing stud h, see Fig. 10, above which is a squared portion h of larger diameter, above which is preferably an enlarged bearing portion h' Above the bearing portion, k is a bearing portion h of less diameter than the part h and extends through a stul'i ing box a. Outside of the stufiing box, the

ivot stem is provided with suitable means for turning it by hand, consisting in this instance of a squared portion h adapted to receive a socket wrench or handle or other de-v vice by which it may be turned. The pivot stem is fitted in the part A contiguous to the valve chamber a, as shov. n in Fig. 10 and a suitable packing h is interposed bet een the stufling box and the hearing portion h, as shovv n. H represents an arm or lever having at one end a squared opening fitting the squared portion h of the stem, and at lts other end a circular aperture engaging the stem 9 of the valve G. It is obvious that by applying a suitable tool to the exterior squared portion h of the stem H, the gate valve G can be instantly sn ung into or out of engagement vvith the exterior seat a of the inlet passage, thus cutting off the apparatus from the water supply or connecting it therewith, as may be desired. The other portlons of the apparatus shown in Fig. 8 are SLIl'LStzllllietially identical in construction and operation ith the corresponding parts illustrated in Figs. 1 to 7 and will not be again described.

In Fig. 11, I have illustrated another slight g modification of the invention, in which the diflerent means for adjustably limiting the valve C in its opening movement, as the washers, previously described with reference to Figs.v 1 to 7, could not be used. In this instance, therefore, I make the main valve C with an exterior sleeve 0 extending through the central portion of the same and provided with an interior threaded opening considerably larger than the stem F. Into this threaded sleeve is screwed the controlling sleeve 0 the bore of which fits around the stem F with a loose fit as reviously described with reference to the s eeve 0 It is apparent that by turning the controlling sleeve 0 the outer end of the sleeve, that is the end nearest the relief valve, can be ad-' j usted toward or from the relief valve so as to limit the opening movements of the main valve C adjustably for the purpose heretofore described. The other parts of the mechanism shown in Fig. 11 are identical in construction and operation with the correspond ing parts shown in Figs. 1 to 7 and will,

' therefore, not be again referredto.
